Voice Enhancements

Description:
The current voice playback feature needs quality improvements to sound more natural and professional.

Current Issues:

• Speech flow is choppy and lacks smooth transitions between words

• Pronunciation errors on certain words

• Robotic delivery without natural cadence or intonation

• While voice character designs are appealing, the actual audio output quality doesn't match

Requested Improvement:
Implement upgraded voice synthesis with smoother speech flow, accurate pronunciation, and natural-sounding delivery that feels less robotic and more human-like.
